How can the small intestine absorb so many nutrients from chyme?

The small intestine absorbs nutrients from chyme through its highly specialized structure, which includes a large surface area created by villi and microvilli. These projections increase the absorptive capacity, allowing efficient uptake of nutrients like amino acids, sugars, and fatty acids. Additionally, the small intestine has a rich blood supply and specialized transport mechanisms, including active and passive transport, to facilitate the movement of nutrients into the bloodstream. Enzymatic digestion also plays a crucial role, breaking down complex molecules into simpler forms that can be easily absorbed.
